— SACE Tmax XT molded case switches (MCS)
Molded case switches are devices created from the corresponding circuit-breakers and feature the same overall dimensions, versions, and can be fitted with the same accessories.
Applications These devices are mainly used as:
In the open position, the switch guarantees a sufficient insulation distance (between the con- tacts) to ensure safety and to prevent an electrical arc from striking.
• general disconnection devices in sub-switchboards; • switching and insulation devices for lines, bus bars or groups of apparatus; • bus ties.
